Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78402, here are decompositions:

  • 61 + 78341 = 78402
  • 101 + 78301 = 78402
  • 173 + 78229 = 78402
  • 199 + 78203 = 78402
  • 211 + 78191 = 78402
  • 223 + 78179 = 78402
  • 229 + 78173 = 78402
  • 239 + 78163 = 78402

Showing the first eight; more decompositions exist.
